You can pay for your signup fee by PayPal or bitcoin. Then, you can transfer USD funds by bank wire, PayPal, or bitcoin into your "virtual account" at PacMe. We prefer that you keep money on account with us, and it will be much cheaper for you as well. If you use a non-US credit card, your bank might not always accept a charge from us, they will likely charge you a hefty foreign transaction fee, or they might give you a poor exchange rate.
